Not sure what size Freedom Harness or dog collar to order for your dog? See below for size charts and measurement instructions! Please note: There is a different chart for Martingale Collars vs. Side Release (buckle) or Buckle Martingales. Freedom Harness Sizing Chart and Measuring Instructions To measure your dog for the Freedom No Pull Harness, take a soft measurement tape and measure all the way around the largest part of the chest, right behind the front legs. Then, you can choose the *smallest* size that still fits your dog. So for example, if your dog's chest measurement is 28" exactly, we still recommend that you choose the size Medium, as the front straps will be a better fit. PS The 5/8" Medium and 1" Medium fits the same chest measurement range. If your dog's average weight is 32lbs - 40lbs, choose the 5/8" Medium. If your dog's average weight is 40lbs - 60lbs, choose the 1" Medium. ”
